Looking to build a 10" 300 BLK that will be run primarily suppressed. Trying to find a bullet / powder combination that would be best out of a 10" 300 BLK barrel. By best, what I'm looking for is
- clean burning
- actually subsonic
Bullets and Powder are coming back online (mostly) so getting it isn't my concern.
I'll likely pick up virgin Starline 300 BLK brass (seems about the only one available currently) OR do I pick up 223 brass that has been formed to 300 BLK? Obviously it requires a lot to mix up 300 BLK from 223, but I'm also one to prefer my headstamp say what it is.
I have tons of SRP and some SMRP (wolf magnums).
